Alright I've been here now many times since it's close to my in laws so I'm ready to report :-P
It is super quick, no doubt. Even when I order something with a couple of changes or extra requests, by the time I get to the window, they are handing me my receipt and my food.
Their portions are very very filling. I usually get the cobb and add chicken (protein, baby, yeah!!) and I used to get the accompanying dressing but it's a little high on the calories so I skip it now. My kids get a wrap or a smoothie which I appreciate have very simple, clean ingredients and are what I myself would make at home (but obviously not if I'm running around with errands!). We rarely do eating out when it's the kids and I but on some occasions I have stopped here for the convenience. And I will continue to!
